Title:
移動体遠隔制御システム
Document Type and Number:
Japanese Patent JP4003707
Kind Code:
B2
Abstract:
To enhance a coupling sensitivity between a coupler mounted on a traveling object and a guide line.
A coupler 20 formed to be a loop is mounted on the mobile body so that the coupler 20 is close to a parallel feeder 10 comprising two parallel lines to couple the mobile body to the feeder 10. Since an insulated inner conductor is placed in the inside of the coupler and the surrounding of the inner conductor is shielded by an outer conductor and magnetic coupling is mainly adopted, the strength of a very weak high frequency signal usable for communication can be increased.
